Introduction
Mumps refers to acute infectious disease of respiratory tract due to mumps virus. The clinical symptoms are non-suppurative swelling of the parotid gland, pain, fever, restricted activity in chewing and involvement of various glands or viscera. Usually the prognosis is favorable. A few cases tend to develop complications like orchitis, encephalitis, meningitis, pancreatitis and ovaritis. This disease usually occurs in winter and spring among children. It is often caused by exogenous wind and warmth that stagnate shaoyang and yangming meridians. Severe attack by pathogenic factors may involve the liver meridian and lead to swelling and pain of testis. Invasion of exuberant pathogenic toxin into the pericardium may generate liver wind by extreme heat and result in deteriorated syndrome.

Syndrome Differentiation
1. Stagnation of Wind-Heat
Parotid swelling and pain, difficulty in chewing, accompanied by aversion to cold, fever, headache, general aching sensation, thin and yellow tongue fur, and floating and rapid pulse.

2. Exuberance of Pathogenic Toxin
Parotic swelling and unpressable pain, difficulty in chewing, sore throat, lingering high fever, restless thirst with desire to drink, headache, red tongue with yellow fur, slippery and rapid pulse. Stagnation of heat in the liver meridian may lead to swelling and pain of testis, dragging pain in the lower abdomen, or even chills and high fever. Inner sinking of virulence may result in sudden high fever, severe headache, stiff neck, or even coma, convulsion, red tongue with yellow fur, or deep-red tongue with scanty fur, large and rapid or thin and rapid pulse.
